Abstract
OBJECTIVES
Non-A non-B aortic dissections are rare, and little is known about their natural history, indications for surgery and operative results. We aim to examine the literature to ...summarize what is known of the natural history of non-A non-B dissections and evaluate the outcomes of the therapeutic options available.
METHODS
An extensive literature search was performed using MEDLINE to find all published studies that report data on the natural history and outcomes of patients with non-A non-B aortic dissection. Data on patients treated with medical therapy were extracted to characterize the natural history. Primary end points included 30-day mortality, stroke and retrograde type A dissection.
RESULTS
Of the 423 studies found, 14 articles (433 patients) fulfilled the inclusion criteria for quantitative analysis. The proportion of medically treated patients ranged from 5 to 54% with a pooled rate of 36% (50/138). The 30-day mortality of patients treated with medical therapy was 14% (7/50). The overall estimated proportion of 30-day mortality for patients who underwent intervention was 3.6% 95% confidence interval (CI) 1.7–5.6%, retrograde type A dissection was 2.6% (95% CI 0.8–4.4%) and stroke was 2.8% (95% CI 1.0–4.5%).
CONCLUSIONS
Despite the likelihood of reporting and selection bias, patients with non-A non-B dissection often have a complicated course requiring some form of intervention. The 30-day mortality of patients treated with medical therapy seems higher than surgical or endovascular therapy. Ideally, further large prospective studies are necessary to confirm our suggestion that early intervention may be indicated in non-A non-B dissections.
Due to the increase in average life expectancy and the higher incidence of cardiovascular disease with advancing age, more elderly patients present for cardiac surgery nowadays. Advances in pre- and ...postoperative care have led to the possibility that an increasing number of elderly patients can be operated on safely and with a satisfactory outcome. Currently, coronary artery bypass surgery, aortic and mitral valve surgery, and major surgery of the aorta are performed in elderly patients. The data available show that most cardiac surgical procedures can be performed in elderly patients with a satisfactory outcome. Nevertheless, the risk for these patients is only acceptable in the absence of comorbidities. In particular, renal dysfunction, cerebrovascular disease, and poor clinical state are associated with a worse outcome in elderly patients. Careful patient selection, flawless surgery, meticulous hemostasis, perfect anesthesia, and adequate myocardial protection are basic requirements for the success of cardiac surgery in elderly patients. The care of elderly cardiac surgical patients can be improved only through the strict collaboration of geriatricians, anesthesiologists, cardiologists, and cardiac surgeons, in order to obtain a tailored treatment for each individual patient.
Abstract Advanced chronic kidney disease (CKD) is associated with poor outcomes in patients undergoing surgical aortic valve replacement while its prognostic role in transcatheter aortic valve ...implantation (TAVI) remains unclear. This study aimed to investigate outcomes in patients with advanced CKD undergoing TAVI. 1904 consecutive patients undergoing balloon-expandable TAVI in 33 centers between 2007-2012 were enrolled in the I talian T ranscatheter Balloon- E xpandable Valve Implantation R egistry (ITER). Advanced CKD was defined according to estimated glomerular filtration rate (eGFR): 15-29 mL/min/1.73m2 stage 4 (S4), <15 mL/min/1.73m2 stage 5 (S5). Edwards Sapien or Sapien-XT prosthesis were used. Primary end-point was all-cause mortality during follow-up. Secondary end-points were 30-days and FU major-adverse-cardiac-events (MACE), defined with VARC-2 criteria. 421 patients were staged S5 (n=74) or S4 (n=347). S5 patients were younger, had more frequently porcelain aorta and lower incidence of previous stroke. Peri-procedural and 30-days outcomes were similar in S5 and S4 patients. During a 670 (±466) days of FU, S5 patients suffered higher mortality rates (69% vs. 39%, p<0.01) and cardiac death (19% vs. 9%, p=0.02) compared to S4. Male sex (HR 1.6, 95%CI 1.2-2.2), LVEF<30% (HR 2.3, 95% CI: 1.3-4), atrial fibrillation (HR 1.4, 95%CI:1.0-1.9) and S5 CKD (HR 1.5, 95%CI: 1.0-2.1) were independent predictors of death. In conclusion, TAVI in pre-dialytic or dialytic patients (i.e. S5) is independently associated with poor outcomes with more than double risk of death compared to patients with stage 4 renal function. Conversely, in severe CKD (i.e. S4) a rigorous risk stratification is required to avoid the risk of futility risk.
Koch’s Bacillus bovis (Mycobacterium bovis) was made avirulent by special culture conditions, i.e., 230 passages on medium containing potatoes treated with bile salts. It has been used mainly to ...prevent tuberculosis. The vaccine was named after the bacteriologist Albert Calmette and the veterinarian Camille Guérin, i.e., Bacillus Calmette-Guérin (BCG). These researchers worked at the Pasteur Institute in Lille and launched the vaccine in 1921.Recently, BCG was used also for its non-specific immunostimulant action. Intravesical administration of BCG is an adjunctive therapy for the treatment of bladder cancer, which does not invade the muscle wall.We will discuss the clinical case of a patient who had fever of unknown origin for about 2 months and was resistant to treatment with multiple lines of antibiotics.
Since the advent of TAVR (transcatheter aortic valve replacement), the transapical surgical approach has been affirmed as a safe and effective alternative access for patients with unsuitable ...peripheral arteries. With the improvement of devices for transfemoral approach and the development of other alternative accesses, the number of transapical procedures has decreased significantly worldwide. The left ventricular apex, however, has proved to be a safe and valid alternative access for various other structural heart procedures such as mitral valve repair, mitral valve-in-valve or valve-in-ring replacement, transcatheter mitral valve replacement (TMVR), transcatheter mitral paravalvular leak repair, and thoracic aorta endovascular repair (TEVAR). We review the literature and our experience of various hybrid transcatheter structural heart procedures using the transapical surgical approach and discuss pros and cons.
Common variable immunodeficiency (CVID) is a rare disorder characterized by primary antibody deficiency leading to hypogammaglobulinemia and increased risk of infections. Pulmonary hypertension (PH) ...is an unusual complication of CVID and may be associated with chronic hypoxemic respiratory failure.We described the case of a 47-year-old female patient hospitalized with worsening dyspnea, which had emerged about 10 days before and was associated with productive cough. 26 years before, she was diagnosed with common variable hypogammaglobulinemia, that was treated with intravenous immunoglobulin infusions for at least 20 years. She had suffered from recurrent secondary infections of the respiratory tract with inveterate bronchiectasis, pulmonary hypertension, and chronic respiratory failure.This case suggests that Internal Medicine wards, due to their global vision of the patient, are well suited to manage subjects with serious, complex, and genetically determined pathologies.
Background Transcatheter aortic valve implantation (TAVI) has been proposed as a therapeutic option for high-risk or inoperable patients with severe symptomatic aortic valve stenosis. The aim of this ...multicenter study was to assess early and medium term outcomes of transapical aortic valve implantation (TA-TAVI). Methods From April 2008 through June 2012, a total of 774 patients were enrolled in the Italian Registry of Trans-Apical Aortic Valve Implantation (I-TA). Twenty-one centers were included in the I-TA registry. Outcomes were also analyzed according to the impact of the learning curve (first 50% cases versus second 50% cases of each center) and of the procedural volume (high-volume versus low-volume centers). Results Mean age was 81.0 ± 6.7 years, mean logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) I, EuroSCORE II, and The Society of Thoracic Surgeons risk score were 25.6% ± 16.3%, 9.4% ± 11.0%, and 10.6% ± 8.5%, respectively. Median follow-up was 12 months (range, 1 to 44). Thirty-day mortality was 9.9% (77 patients). Overall 1-, 2-, and 3-year survival was 81.7% ± 1.5%, 76.1% ± 1.9%, and 67.6% ± 3.2%, respectively. Thirty-day mortality of the first 50% patients of each center was higher when compared with the second half ( p = 0.04) but 3-year survival was not different ( p = 0.64). Conversely, 30-day mortality at low-volume centers versus high-volume centers was similar ( p = 0.22). At discharge, peak and mean transprosthetic gradients were 21.0 ± 10.3 mm Hg and 10.2 ± 4.1 mm Hg, respectively. These values remained stable 12 and 24 months after surgery. Conclusions Transapical TAVI provides good results in terms of early and midterm clinical and hemodynamic outcomes. Thus it appears to be a safe and effective alternative treatment for patients who are inoperable or have high surgical risk.
We describe the case of a 53-year-old man, recently diagnosed with decompensated type II diabetes mellitus, admitted to our Department for fever, asthenia, and detection of multiple lung abscesses ...and pulmonary embolism at chest tomography.His clinical history revealed just a recent orthopedic surgery of osteosynthesis on the left wrist with normal clinical and instrumental post-surgical evolution. Empirical antibiotic therapy with piperacillin/tazobactam and clindamycin was initiated. During hospital stay, swelling and functional impotence in the right knee occurred. They were investigated by arthrocentesis and magnetic resonance, and diagnosed as septic arthritis.Blood culture performed at admission tested positive for Citrobacter koseri on several samples where meropenem was added according to antibiogram. On the other hand, the cultures of bronchoaspirate, pulmonary fine needle aspiration, and arthrocentesis were negative.Antibiotic therapy was administered up to two weeks after discharge and radiological and physical features progressively improved.
Surgical coronary revascularization and percutaneous coronary intervention were demonstrated to be effective treatments for coronary artery disease. However, the optimal revascularization strategy ...remains unclear in certain patient subsets. The recently published Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease (FREEDOM) trial is a randomized study evaluating the use of CABG versus PCI in diabetic patients with multivessel coronary disease. The purpose of this study was to review the available literature based on randomized trials and observational studies in order to allow clinicians to make evidence-based decisions when treating diabetic patients with multivessel coronary disease. The current evidence suggests that CABG should remain the standard of care for this patient population.
Objectives Patient selection is crucial to achieve good outcomes and to avoid futile procedures in patients undergoing transcatheter aortic valve replacement. The aim of this multicenter ...retrospective study was to identify independent predictors of 1-year mortality in patients surviving after transapical transcatheter aortic valve replacement. Methods We analyzed data from the Italian registry of transapical transcatheter aortic valve replacement that includes patients undergoing operation in 21 centers from 2007 to 2012. Futility was defined as mortality within 1 year after transapical transcatheter aortic valve replacement in patients surviving at 30 days. Thirty-day survivors were divided in 2 groups: futility (group F) and nonfutility (group NF). Cox proportional hazard regression analysis was performed to identify independent predictors of futility. Results We analyzed data from 645 patients with survival of 30 days or more after transapical transcatheter aortic valve replacement. Groups F and NF included 60 patients (10.8%) and 585 patients (89.2%), respectively. Patients in group F were more likely to have insulin-dependent diabetes (15% vs 7.2%, P = .03), creatinine 2.0 mg/dL or greater or dialysis (18.3% vs 8.2%, P = .01), logistic European System for Cardiac Operative Risk Evaluation greater than 20% (66.7% vs 50.3%, P = .02), preoperative rhythm disorders (40% vs 25.3%, P = .03), critical preoperative state (8.3% vs 1.8%, P = .002), and left ventricular ejection fraction less than 30% (15% vs 2.9%, P < .001). The multivariate analysis identified the following as independent predictors of futility: insulin-dependent diabetes (odds ratio, 3.1; P = .003), creatinine 2.0 mg/dL or greater or dialysis (odds ratio, 2.52; P = .012), preoperative rhythm disorders (odds ratio, 1.88; P = .04), and left ventricular ejection fraction less than 30% (odds ratio, 4.34; P = .001). Conclusions According to our data, among patients undergoing transapical transcatheter aortic valve replacement, those with insulin-dependent diabetes, advanced chronic kidney disease, rhythm disorders, and low left ventricular ejection fraction have a higher risk to undergo futile procedures.
